Submersible Pump

A submersible pump is designed to operate with both pump body and motor submerged in the pumping fluid. A hermetically sealed and close-coupled motor allow the pump to be completely submerged.


Advantages: These types of pumps eliminate the need for a dry vault next to a wet well. Submersible pump stations are also less expensive to construct because only a wet pit is needed, and there's no need for above ground construction to house a control center, just a cabinet above the pit.

Disadvantages: Submersible pumps are not readily accessible, therefore they're very difficult to troubleshoot. Typically, the pump fails before a problem is detected.

Mechanical seal or cable failure can lead to moisture in the motor housing.
When selecting a pump for wastewater applications, consider your plant's priorities. Focused on reliability? Choose a pump that allows for regular inspection. Focused on lower cost? 

Choose a pump that requires less upfront installation cost. Not sure which one will best help reach your goals? Talk to an engineer who is well versed in wastewater applications.

Dry Pit Submersible Pumps

A hybrid of submersible and dry-pit pumps, the dry-pit submersible runs continuously in dry, or submerged conditions.

Unlike dry-pit pumps, the motor is mounted directly to the pump, eliminating the intermediate shaft. The pump uses sewage or glycol to cool the motor while running.

Advantages: These types of pumps are highly resistant to flooding damage. They also have a compact design (due to the close coupled motor), great for applications where space is limited.

Disadvantages: Mechanical seal failure can lead to moisture in the motor housing. Sewage cooled motors can also experience problems when particles from the sewage settle out and are not properly flushed. This can lead to overheating of the motor.

  1.Operating principle: In the system,all of solar collectors put togerther,each household have a heat storage tank,heat storage tank has heat exchange device and electric auxiliary heating device inside,control system 、 circulation device and other auxiliary device,solar collectors which is placed together absorb sunlight and convert heat,temperature rised.According to the temperature difference between solar collector and water tank,Control system loop starting,medium is loop between solar collector and lots of heat exchange device for heat storage tank,the medium uses the water between heat-exchange and heat-storage tank to do heat exchange,then heat the water in the heat storage tank. Hot water supply mode:adopt top-water type to supply water,to ensure that the hot and cold water supply homologous and isobaric,easy to use.solar system conbimed with normal energy(electricity) to ensure that can supply hot water whole day. 2.

How to Size a Submersible Water Pump

For outdoor projects requiring water flow, a submersible  water pump in Dubai , UAE is a popular and useful choice. Not only do wells use them, but they’re commonly found in ponds, water gardens, fountains, waterfalls and other lawn features with spouts. Submersible pumps are economic ways to circulate water in ponds and other lawn features. Not only are they fully submersed in water and completely free of noise, but they can be used to drain ponds as well. For any project, it’s important to size your pump correctly. Here’s a closer look at some of the common recommendations to follow when sizing your submersible water pump: Well capacity:  One of the most obvious measurements you need to size your water pump is the capacity of your well or other water project. The larger the well, the greater the requirements for the pump. However, modifications sometimes can be made to the pump to correct insufficient water capacity. Performance curve:  It’s important to achieve a b...
